The effect of substrate concentration on enzyme activity

WebIf, as is often the case, the law of mass action is followed, it is, of course, the dissociation constant of the enzyme-substrate compound, and the reciprocal of the affinity constant. WebEnzymes are highly specific catalysts for biochemical reactions, ... and is an inverse measure of the substrate's affinity for the enzyme—as a small \(K_m\) indicates high affinity, meaning that the rate will approach \(V_{max}\) more quickly. The value of \(K_m\) is dependent on both the enzyme and the substrate, as well as conditions such ... fh5 free credits

10.6: Allosteric Interactions - Chemistry LibreTexts

WebAn enzyme's K m describes the substrate concentration at which half the enzyme's active sites are occupied by substrate. A high K m means a lot of substrate must be present to … WebSep 19, 2024 · Enzymes catalyse a reaction by reducing the activation energy needed for the reaction to occur. However, enzymes need to be tightly regulated to ensure that levels of the product do not rise to undesired levels. This is accomplished by enzyme inhibition. ... Allosteric enzymes have two states: a low affinity state dubbed the “T” state and ...
